LMV600TM Restore/Ugrade Guide a12

[hooutoo]

This restore process is intended for the Tmob V60 (lmv600tm) model and you must WIPE your data so back it up if you want to keep it!

This process will restore the lmv600tm to the state directly after the ota upgrade to the a12 v30b build. I’ve dumped all the required partitions from a MY personal lmv600tm. This process uses the Qfil utility and assumes you already have a working knowledge of Qfil and that you have already installed it on your Windows PC. If you don’t have that knowledge start reading. The internet is full of Qfil guides.

You can’t damage or fix your existing imei relevant partitions from this restore because they aren’t included in this download.

You are responsible for backing up your existing phone partitions. I’m not liable for you using my work product and you do so at your own risk. If you’re unsure of what you’re doing then read more about Qfil and what is does. Again, if you are a newby go slow. Taking your time will save you a lot of aggravation.

This process will not fix your erased or damage imei number problem. There are process out there but they are usually reserved for people with an expert level of knowledge on the subject.

This guide is for anyone who’s presently unable to boot or who just can’t access Tmob ota services and wishes to upgrade their lmv600tm to the a12 build. I have only tried this when my phone was already on an Android 11 rom. That’s not to say it won’t work coming from a Android 10 rom but I haven’t tried it.

This process will not fix your erased or damage imei number problem.

Steps

Download “Lmv600tm v30b Restore Partitions.7z” file from ???? and unzip. Remember the unzipped restore directory path.

Download “DriverBootandFirehose.zip” file from here and unzip. Remember the unzipped location.

Plug your phone into PC with USB cable and put you phone in EDL (9008) mode. Again, there are guides on how to do this everywhere.

Start Qfil and select the port of your phone’ connection. (See Windows device manager)

Select the v60 firehose from where you unzipped “DriverBootandFirehose.zip”.

Select storage type = ulf which is located at the bottom right of the Qfil dialog screen. I’m using Qfil 2.0.3.5 version.

Next click on the “load XML” button and group select “rawprogram0” thru “rawprogram6” which are also in the unzipped directory, then hit OK. Next it will ask for the Patch0.xml file, hit cancel as we’re not patching anything.

Wait a few seconds and then click on the “Download” button. Qfil will now resolve all the names of the partitions to be restore and then start the download process to the phone.

When complete phone reboots as I recall.

[hooutoo]

As per the op this is for the T-Mobile model. I haven’t tested on the AT&T model.

You won't need userdata on a reflash.

Did you manage to do this?

I can confirm that a LGV600Am -> LGV600TM works*. It is possible to crossflash a ATT (A10) to T-Mobile (A12) LG v60!* Yay and TY. As stated elsewhere good luck with 5G. It is suspected T-Mo is blacklisting LG now? My FingerPrint reader is broken. I had to use a weird hidden menu trick on the stock Att A10 when bootloader unlocked. This guide worked perfect except the firehose! Someone is handing out the prog__ufs_firehose_sm8250_ddr.elf and not correct file named prog__ufs_firehose_sm8250_lge.elf! I kept getting QFIL errors! I attached the proper version. Its getting hard to find for free!
Still learning about treble generation. Thanks for the dump! Hopefully there is a newer june/july update.

PS: Welp unlocked bootloader causes failed update & lg switch key attestation/ key deleted error. I would appreciate any help w/ 5G would be nice but not needed.


*= Broken 5G and No Fingerprint registration.

I update my T-Mobile version from A11 to A12 and encounter the same problem.
Using the .elf file from https://forum.xda-developers.com/t/v60-bootloader-unlock-and-magisk-root.4358785/ (probably the same as you provided because both files share the same name) and updated the system successfully.
The bootloader unlock state is perserved (unlocked). However, I also find that the fingerprinter is broken (Enrollment was not completed: Fingerprint enrollment time limit reached).

Edit:
Fingerprint can be fixed by following the guide in https://forum.xda-developers.com/t/v60-bootloader-unlock-and-magisk-root.4358785/

Thanks above for this and to OP for the original walkthrough this saved my bootlooped device! Took me a couple tries to get QFIL to start the process but it worked for me.

Also if you're a v60 neophyte like me you can follow the first 4 steps from the bootloader unlock thread to get QFIL setup to run the OP's restore process.

Yeah the FP doesnt work period (or random) on custom roms. 4got that part. I was able to get it working prior with a different post about accessing testing/service menu on Stock ROM. Ty anyway. I cannot type on laptop anymore b/c touch phone. Seems hit & miss. Im going to do a full kdz restore. I will be able to download the latest update. I may link it when I do.

My thinking is the a/b schemes. So I am super grateful for the flash files. I did some minor prodding and the files were initially for EA series. I saw build props & stuff that said so. My thinking is there is a Vendor &or Product partition update thats needed. Most likely a full up to date Vendor from US carriers.

Unfortunately an unlocked boot-loader deletes Google Certs. This is because the (unlock magic) Engineering or Test BL thats around is not signed or more likely not matching the rest of the boot chain.

I dont really know of a better way to access 5G info other than the *#INFO or phone util app.
I choose NR/LTE, then menu select band. Now interesting things happen here. Selecting US gets LTE but if I select Auto then I get LTE+...

jeez all of this b/c my replacement Note10+ was locked and unlock dude died from COVID (or is being held by Samsung all Umbrella Corp style). Apparently nobody else has the keys or license.

lastly sorry about length & incompleteness of dialer codes. I said yeh lets update Corvus using updater. When it was done it said done & slot switched! My other partition was full stock! Now I got bootloops. Im experimenting w/ dualboot...

I also found that OTA updates fails w/ unlocked bootloader (didn't test on locked bootloader). Because of that I even don't have the chance to change the slot. I thought that it was the R/O system partition that caused the problem.

'unlocked boot-loader deletes Google Certs', I don't know the consequence of deleted Google Certs, willing to explain more?

I currently don't have a 5G SIM so I can't have a test on 5G problem.
